Definitions
- the present invention relates to functionalized multiblock macromonomers containing at least one (meth)acrylic sequence, and to a process for their production.
- Triblock copolymers combining alkyl methacrylate blocks of different types are already known.
- Polymer Preprints 29(1), pages 343-345 describes triblock copolymers (tert-butyl methacrylate-b-2-ethylhexyl methacrylate-b-tert-butyl methacrylate) obtained by anionic polymerization in tetrahydrofuran at -78° C. in the presence of a difunctional initiator.
- Block copolymers which are able to contain up to 20% by weight of tert-butyl methacrylate but which have a relatively wide molecular weight distribution are obtained by this method.
- the combination of various methacrylates in a triblock copolymer of this type does not appear to be able to confer on this copolymer, even after subsequent hydrolysis and/or neutralization of the ester groups, properties which render it suitable for a particular application.
- the combination, in a triblock copolymer, of acrylate blocks and methacrylate or vinylaromatic blocks appears capable, provided that the copolymer has a narrow molecular weight distribution, of providing properties of value in several types of application.
